Title: Stabilization of glass feed in fiberization  by toration
Inventor: LEVECQUE MARCEL
IPC: D01D5/14
Filed: 1979-11-27
Granted: 1982-09-07
Abstract: Abstract of the Disclosure:          Method and apparatus are disclosed providing both for separation of the components of a toration fiberizing center, including separation of both the glass stream supply means and of the secondary or carrier jet from the blast, and at the same time further providing for stabilization of the feed of the glass into the system, notwithstand-ing the separation of the components.  This is accomplished by shielding the jet flow from induced air at one side of the jet and introducing the glass stream into the influence of the induced air at the opposite side of the jet.

Abstract: Abstract of the Disclosure In a microprogrammed data processing system the throughput of the sys-tem is increased during the processing of decimal numeric instructions by appara-tus which is conditioned by the instruction descriptors in advance of receiving the operands to align the decimal digits of the operand words as the words are received by the apparatus from memory.  The descriptor information for each oper-and includes the scale factor, the position of the sign, the position of the most significant character within the word, whether it is a floating point or scaled operand, the number of bits in each decimal character, either 4 or 9 bits and the length of the operand.  The apparatus is conditioned by the descriptor informa-tion to align the two operands for processing.  The apparatus indicates to the microprogram the characteristics of the operand being processed thereby enabling the proper microprogram subroutine, that is, if the operand is a floating point or a scaled number, has 4-bit decimal digits or 9-bit decimal digits, has an over-punched leading sign or trailing sign, has an adjusted length less than or equal to 63 decimal digits, whether the operand is a long or short operand, and whether the resulting operand is equal to zero or has an overflow.  The apparatus receives a long operand, greater than a predetermined number of words, which is the result of the calculation, assembles the resultant operand in accordance with an instruc-tion descriptor, and transfers the resultant operand to memory.  In response to a microword indicating that the result of the decimal numeric calculation is a short operand, that is, a predetermined number of words or less, and in accord-ance with an instruction descriptor, the apparatus generates a count of the number of words of the resultant operand, the decimal unit will transfer to memory.

Abstract: System for controlling the direction of the momentum vector of a geosynchronous satellite ABSTRACT OF THE DISCLOSURE      A system for compensating the disturbance torques applied to a satellite, which eliminates the requirement for a thruster control loop. The disturbance torque itself is used as the compensating torque in order to super-impose to the incidental misalignment of the solar panel arrays an artificial misalignment that can cause the momentum vector to be adjusted to the desired direction in order to restore the correct attitude of the satellite. The direction of the momentum vector is controlled in orbit only by solar sailing, that is by organizing at prescribed times suitable manoeuvres of one of the solar panels in order to adjust the solar panel array configuration when the roll angle of the satellite exceeds a determined threshold value.

The vessel includes a submersed element for cutting branches of the vegetation and means for gathering, raising and transfer-ring the branches in a rearward direction.  The vessel includes a float-ing assembly comprising two side and elongated floats which hold an upper platform containing a command both and a power plant.  A water tunnel is formed under the platform.  Driven helices are located in the front part of the tunnel, the helices being adapted to drive the water within the tunnel in a backward direction.  The driving means for the vessel include the helices in combination with blade wheels at the sides of the floats, the blade wheels having driving forces which may be controlled in independent and selective directions.  The cutting element is located behind the first helices and at an adjustable level below the level of the helices.  A branch-gathering net is disposed behind the cutting element, the net having its bottom formed by an inclined plane which assends in a rearward direction, the net being open and communicating with a cage for receiving the branches.          The net and the tunnel thus form the means for gathering, raising and transferring the branches in a backward direction.  This vessel is chara-cterized by its high effectiveness and by a higher yield of the power needed for its operation, with respect to the gathering means per se, with respect to the means used in the conditioning of the crop material, and with respect to the operation of the driving means.
